I have a problem with sending OleVar_Null to OCX control. I trying to
execute method Add of the standart TreeView control. The first time
parametr relation must be Null. How to send Variant null parametr to
OCX control (OleVar_Null do not work,
v number:=Null;
to_Variant(v); - do not work too).
If I sending all OleVar_Null parametrs, in this case all work well.
When some of the first parametrs are not null, others - OleVar_Null,
all right. When one or more of the previsios parametrs are OleVar_Null,
and one or more of nexts parametrs are having value - OCX error 100504 -
wrong number or type parametrs.
